OBJECTIVES ▪ To take advantage of Mexican natural resources in order to benefit communities, giving an added value to their agricultural products. ▪ Mexican Technological Development, to be capable of giving both a technically and economically viable solution to the issue of the horticultural spoilage and waste in our country. ▪ Generate innovative research, human resources, academic, scientific and technological linkage. ▪Promote entrepreneurs that generate new jobs
SITUATIONS AND OPPORTUNITIES
In Mexico are wasted close to
37 %
the food, which is prodeced per year:
10 million 431 thousand tons of food per year

DEHYDRATOR DESIGN AND LABORATORY
TESTS
DESIGN CONDITIONS:
Hot air at 65 ° C
Air speed of 1.5 to 3 [m / s] in the
cabinet
Load of raw material per batch: 10 kg.
Dehydrated product per batch: 0.200 kg
(depending on the product)
Hot water at 70 ° C
TESTING
Various tests have been carried out in order
to characterize the technology, determining
the operative parameters appropriate to the
dehydration process, as well as
characterizing the drying curves for each of
the different horticultural products analyzed.
NUMERIC SIMULATIONS
Different geometric configurations were investigated and analyzed based on commercial technologies.
In order to improve the simulation models,
data was collected that allowed to make the
results more assertive
RIA 2018 of numerical simulation for
future designs.
DGAINSTRUMENTATION The instrumentation of the prototypes allows to acquire information to feed the simulation models and, also, allows to have a better control of the dehydration process. The main variables that are monitored are: Temperature Humidity Windspeed

FUTURE WORKS
PROJECT DGA200
We are working on a prototype with greater production
capacity.
Characteristics:
Processing up to 200 [kg] of dehydrated food
Operation continues 24 [hrs.] Of the day
Ability to process various foods of fruit and vegetable
origin
Operates with geothermal energy, but can be adapted
to work with industrial energy remnants
Better quality in dehydration and shorter processing time
per batch, due to its improved distribution of flow and
IA2018 temperature. RDGA80 INSTALATION RIA2018
DGA DGA200
Patent pending for modular food
dehydrator.
Once the DGA200 is operable,
the patent will be searched.
